Serial Interface Connector

The serial communication interface transfers either 7-bit or 8-bit character information in an asynchronous, bit-serial format. This format is useful for transferring data over long distance lines via data communication devices such as modems, but it can also be used to transfer data directly between the host and the printer. The following table lists the serial interface signals.

	Serial Interface Signals
Signal	Name	EIA	CCITT		Pin	Source

PG	Protective ground	AA		101	1
TD	Transmit data	BA		103	2	Printer
RD	Receive data	BB		104	3	Host
RTS	Request to send	CA		105	4	Printer
CTS	Clear to send	CB		106	5	Host
DSR	Data set ready	CC		107	6	Host
SG	Signal ground	AB		102	7
DCD	Data carrier detect	CF		109	8	Host
R/B	Ready/busy	—	—	11		Printer
DTR	Data terminal ready	CD		108.2	20	Printer

Interface Connection

You can connect your printer to the host computer either directly via an interface cable or through a system of modems and telephone lines with an interface cable at each end of the system. The setup menu structure provides settings (DIRECT CONNECT and MODEM CONNECT) for each of these choices.
